Plans have been submitted for the £30m revamp of one of Wales's top theatres.
Bosses of Theatr Clwyd in Mold want to redevelop its landmark building which was built in 1976.
Under the project there would a timber foyer extension at the front of building with the demolition of the central staircase, as well as a workshop extension at the back.
There would also be internal alterations and refurbishment throughout.
If planning permission is secured construction could begin in 2021.
Planning permission has been submitted by site owner Flintshire council.
Liam Evans Ford, executive director at the theatre, previously said: "We are thrilled to be moving towards the next stage of this once-in-a-lifetime project to secure the future of Theatr Clwyd and safeguard its economic impact in north east Wales worth over £7.7m annually.
"The project will also ensure that North Wales continues to export world class theatre and build upon the 500,000 people who have seen a Theatr Clwyd production elsewhere in the UK over the last two years.”
The new building is set to be "greener", and will include a sensory garden and adventure playground.
There will also be workshops for vulnerable members of the community, as well as a new youth hub and rehearsal and teaching spaces.
Public areas like the bar and cinema, as well as the stage areas, will be completely reimagined, Theatr Clwyd said.
The theatre will remain open throughout the development, with a phased construction ensuring performances can continue on site, with a 300-seater pop-up theatre created next to the main building.
The project will aim to be funded by the Welsh Government, trusts and foundations and private philanthropy, with match funding from Arts Council Wales and support from Flintshire County Council.
